Inclined Plane Flow

Submitted by pnkumar on Sat, 12/19/2015 - 08:17

I am new user of LIGGGHTS and I have to study the granular flow on inclined plane with walls .

1. For that should i design the mesh which is already at desired angel or it can be simple plane with walls and gravity with component in x y and z direction.
2. How to design the inclined plane and and used mesh/gran command
3. how to see the simulation animation with LIGGGHTS.

Please any one clarify my doubts.

Regards

both is possible, rotating gravity is easier bc. one can use wall/gran primitive zplane
2. How to design the inclined plane and and used mesh/gran command
use primitive or create in Paraview a Source->Plane, attach a filter->transform, set rotation you want and than save as vtk and than remesh with gmsh -2 -o plane.stl plane.vtk to a stl.
3. how to see the simulation animation with LIGGGHTS.
a) compile liggghts with VTK support and use dump custom/vtk, this files can be directly opened in paraview,
b) download paraview reader from github and use dump custom dump*.liggghts, add reader to manage plugins->load new ..
c) use lpp (search forum because I allway use option b)
To render spheres:
a) attach a filter glyph
b) load PointSprites Plugin and change representation to pointsprites after loading particle data.
maybe this helps: https://drive.google.com/file/d/0B16_X8nrVquiR2ZIa0Ezbk96blU/view?usp=sh...

When I am trying to use paraview to play the simulation it is showing this error

Hello @pnkumar I am also trying to make an input file for liggghts. I also want to make an inclines plane surface with angle. Can I get some idea ? How did you set up in region?
